I am using PS2 on my 03/04 E55.
What tire pressure should I put in the tires?
I put 38psi on all four but they look a little flat to me. Is it normal?
How much PSI do you guys have for yours?

I run with the standard tire pressure recommended on the door sticker. I think it is 35 all around.

So, is your car a 2003 and a half or an early model release 2004?

LOL! At least I entertained myself but it does beg the question...

I run them the same as mentioned @ 35. But, when you are in situations where you will need some more traction out of the hole drop the backs to 27 (some go higher, some go lower).

Thoughts, fellas?

Ask cylinder head he acts like a know it all on here! lol

I have 20's and i use 40 on 4 corners because i live in New York and its pothole city. Is that ok with you cylinder head am i allowed to use 40psi will that effect the way my boost gauge is working or should i check the oil in my flux capaciter first lmfaoo

There is a "placard" on the driver's side doorjamb (the "B-piller") that gives the correct psi for the size tire that came on the car. I replaced the cont's with PS2's and the size remains the same as does the psi. The owners manual also lists the correct psi.

Once again for those that missed it:

The correct pressure for any car or truck is the one that gives the most even tire wear. Too much pressure and you'll get all the wear in the center of the tread area. Too little pressure and the shoulders (inside and out) will show the most wear. For any vehicle, as weight increases, so must the tire pressure used to support it. Typically (but not always), you'll want the pressures higher on the heavier end of the vehicle. The suggested pressures are just that, a suggestion.

I believe Cylinder Head will back me up on this.

Yes, it is an early release of 04, 211 model

I run 38 all around. At least on my 2005, the sticker for recommended tire pressures is inside the door for the gas cap. There are little pictures of people and suitcases to explain the need for greater PSI for greater load.

38psi all around, to protect the rims!

The E63 recommends, 45f, 41r...is that a typo on my b-pillar door jam or does that sound correct to anyone...seems a bit high i think.

NOEZWA0UT55

thats correct! max is prob 51psi

If you have the stockers then I would use the door jam directives but you can also follow what is says on the inside of the gas cap.

I have 19's with PS2's and Evosport recommended 36psi but I run 38psi because I dont want to take a chance on a bent rim via a pothole. These of course are cold temps.

Your tires will have a different max psi number on them but its the car that should determine where your psi's are at.

I 've had my PS2's on for about 6,000 miles with 37 front and 35 rear and have worn rears pretty hard and even in the middle while the front tires still have plenty of tread. I'm wondering if the rear tires would have worn better if I had dropped the PSI to 33, which is where I am now.
